Writing to 4tb external hard drives
« on: May 29, 2014, 01:11:19 »
I can't write from a 1 or 2 tb external drive to a 4tb external drive.  I do this all the time in Windows explorer but get error message that "Unknown Error, 87" when I use M Commander!  Any help is appreciated! David

You did not provide much info so it is hard to say why this is happening for you.

What version do you use ? Is there some additional error information in the application/file operatoin log (Ctrl+L),
What kind of external drives are they USB2/USB3/ESATA/FW/Other ?, What kind of drives ?
What OS are you running, Desktop or Laptop ? very slow or very very fast CPU ?  Anything else that are special, unique for you system ?

It might be that some part of you HW does not support optimized file transfers.

You can turn that off in

Menu > Configuration > Core Settings > File System >
 * Default file operations options
   * Copy And Move
      [.] Automatically detect read/write strategy for file copy
     
   Turn off that setting and restart MC
